ICE CAN.

npimeation med Augustes, 1923. serial No. 659,712.

To all whom t may concern:

Be it known that I, GEORGE M. KLEUGKER, a citizen of the United States, residing at St. Louis city, in the State of Missouri, have invented a certain new and useful Improvement in Ice Cans, of which the following is a specification.

The invention relates to the cans in which water is frozen in the manufacture of cakes of ice, and more particularly to means for supplying air under pressure to the interior of such cans during the ice-making operations. The object of the present invention is to provide an air conduit formed by an interlocked seam formed of the material of juxtaposed walls of the can body` The invention consists in certain details of construction and arrangement by which the above objects are attained, to be hereinafter described and claimed.

The accompanying drawings form a part of this specification and show approved forms. of the invention.

Figure 1 is a perspective view of a can 26 constructed .in accordance with the invention,

partly broken away to show a portion of the interior.

The remaining ligures are o-n a larger scale.

Figure 2 is a plan view of a portion of the rim of a can at one of the lock-seams by which the plates or sheets of metal forming the body of the can are joined.

Figure 3 is a corresponding vertical section taken on the line 34-3 in Figure 2.

Figure 4 is a transverse section taken on the line 4-4 in Figure 3.

Figures 5 and 6 are similar transverse sections showing two forms of lock-seams at corners of the can.

Figure 7 is a transverse section similar to Figure 4, showing the seam on the interior face of the can.

Similar reference numerals indicate the same parts in all the figures where they appear.

Referring to Figures 1 to 4 inclusive, 10 is the body of the can shown as composed of two thick sheets of metal 11 and 12 joined vertically on the two opposite narrow sides of the can, and having a bottom 13. joined to the sides by lines of rivets 14.

The junction of the sheets 11 and 12 is shown as formed by a lock-seam in which a narrow strip 15 along the margin of the sheet 11, on the exterior, is doubled closely upon itself at 16 to double the thickness of 'the sheet on that line and the entire Inargin is then bent upon itself at 17 to form the wide fold 18. The margin of sheet 12 is folded at 19 to inclose the fold at 16 and extends approximately the same distance in width inwardly as the strip 15; the remainder of the margin of sheet 12, as at 20, follows closely the outer face of the fold 18, thus completing the seam and providing an open space or vertical channel 21 extending the full length of the seam.

The lower end of the channel is closed by soldering or otherwise as at 22, and in the upper end is inserted a properly shaped closely fitted plug 23 bored to receive an insert or nipple 24 adapted to be'eonnected by a hose, not shown, to a source of air supply.

Near the bottom of the can, on the interior, is an orifice 25 communicating with the channel 21 and through which air from the channel is delivered to the interior of the can and performs its usual functions in the ice-making operations.

As shown in Figures 1, 2, 3 and 4, the seams are on the exterior of the narrow faces of the can; this location is generally to be preferred especiallyv in cans having the usual vertical angular ridges 26 on the interior faces of the wide sides, serving to produce the desired oppositely located V-grooves in the ice-cake, but the air channels may be formed in the wide sides or may be in lockseains at the corners as at 27 in Figure 5 and 28 in Figure 6, vin communication with the interior of the can through the orifices 29 and 30 respectively; or the lock-seams may be formed on the inner faces of either of the sides, as in Figure 7, each having a channel 31 and orifice 32.

The construction of the seam may be varied; any form adapted to produce the desired air-channel may be employed.

I claim 1. In an ioe can, an interlocked seam formed of interlocked portions of juxtaposed walls of the can and joining the sheets of metal forming the body of such can, said seam having an inclosed channel therein arranged to supply air to the interior of such can.

2. -In an ice can, a vertically extended lock-seam joining the sheets of metalforming the body of such can, said seam having an inclosed channel extending longitudinally thereof, and arranged to supply air to the interior of such can.

3. The ice can ,d esoifibed: having its body formedof sheets 'of' metal lock-steamed together vertically, said seam having an inolosed channel formed therein and extending longitudinally thereof, andan orifice leading from such channel to the interior of such can.

4. The ice can described Yhaving-its, body formed of sheets of metal joinedby 'folding the adjacent margins ofsuoh ,sheets and engaging such folds one Withthe other to produce a vertical seam having Lan inolosed.

channel extending longitudinally ',tlieieof, and an oriiioeleadmg from such channel to the interior of such can.

duce a vertical seam on the exterior of lsaid body, and havingan inolosed channel e2;- tending longitudinally of such Seam, and an orifivoeleading from s uch channel to the in- "teriofof 'su'oh can.

, 6. The ice can desc 'ibed having its body formed of sheets of metal joined by folding the adjaoexlitrnafrginsvof such sheets and enthe iippei'uend o'euoh channel for iending' 5.-,The ioe oandesoribed havingfits body formed of sheets of metal joined by folding" the adjacent margins of such sheets andengaging suohiolds one with the other to Vpronii theieto.

Intestimony that I claim the invention above .set forth I affix my signature hereto.
